I got a cat with metal implat on his back leg. The other rear leg was removed due to implant infection 4 years ago. I forgot to mention that he fell 9 stories and survived with over 10000 usd bill (even he’s living in Thailand with cheaper but good doctors). Now his metal implant on the side of his knee keeps poking out to the surface and I can see it (looks like terminator). This happened before but it heals up until he runs around and the wound opens again. This time, after 2 months of bandages and cone it never heal but never infected. Is it wise to remove the screw that keeps poking out? The hole is about quater cm in diameter and the metel screw is clearly visible.
